Gardner Denver EDF-KB Operating And Service Manual page 38

All materials used in Gardner Denver
compressor units are compatible with
AEON 9000 SP Lubricating Coolant.
Use caution when selecting down-
stream components such as air line
lubricating bowls, gaskets and valve
trim.
AEON 9000 SP Synthetic Lubricant
is not compatible with low nitrile Buna
N or acrylic paints. AEON 9000 SP is
compatible with most air system
downstream components.
Material Safety Data Sheets (MSDS) are available for
all AEON lubricants from your authorized Gardner
Denver distributor or by calling 217–222–5400.
REMOTE MOUNTED ELEVATED COOLER AS-
SEMBLY PROCEDURE – The Compressor package
will be built and tested with the coolers mounted on the
package. On enclosed units, the fan motor will be dis-
connected after test and the vent fan motor connected
in its place. The vent fan will be mounted in the enclo-
sure. A contactor (starter) will be shipped loose and re-
mote mounted with the cooler by others upon start–up
at the job site. The control box will be wired for remote
elevated coolers at the factory.
All requirements of local codes
should be followed.
When connecting pipe fittings to the cooler, support the
threaded coupling with a pipe wrench when tightening
the connection. Use silicone sealant on all steel to alu-
minum threaded connections. All piping should be firm-
ly supported to avoid strain on the cooler manifold and
connections. Flexible connections should be installed
in all interconnecting piping, adjacent to the cooler, to
avoid transmitting piping weight or vibrations to the
cooler elements. Before beginning installations, check
to be sure that no debris or foreign matter remains in
the couplings or cooler bodies. Be certain intercon-
necting piping is clean to avoid clogging the cooler pas-
sages.
FIGURE 5–3 – COOLER DRAIN DETAIL
AFTERCOOLER PIPING – At shutdown of the sys-
tem, all units should be drained completely of conden-
sate if there is any possibility of freezing or corrosion
damage. To help remove the condensate, the cooler
may be tapped per FIGURE 5–3 and a drain cock
installed. After opening the drain cock, blow air into the
cooler from a connection on the opposite side of the
cooler. At the same time the connection on the drain
side of the cooler should be plugged. The drain cock
should be left open until the machines are ready for
start–up.
Failure to remove condensate from an
idle cooler in freezing temperatures
will cause permanent cooler damage.
Drain condensate after system shut-
down. It is the owner/operator's re-
sponsibility to ensure that conden-
sate has been drained and cooler
dried out to prevent cooler damage.
HEAT EXCHANGER (OIL) PIPING – All remote ele-
vated cooler applications must be sent through Engi-
neering for approval and for recommending pipe size.
When the cooling module is removed from the pack-
